  The SAP error message PCNTPM028 indicates that there is a duplicate item number in the system, which is not allowed. This error typically occurs in the context of materials management, production planning, or similar modules where item numbers must be unique.
  Cause:
  The error is triggered when you attempt to create or modify a record (such as a material, BOM, or production order) that includes an item number that already exists in the system. This can happen due to:

  Review Data Migration Processes:
  
  If the error occurred during a data migration, review the data files and processes to ensure that duplicates are handled appropriately before the upload.
